I have a 2010 Challenger RT with 26,000 miles. The pilot bearing when out damaging my clutch assembly, which will have to be replaced. I do not yet know if the Tremec TR-6060 6-speed transmission is damaged. I have checked around and have been unable to locate an industry rebuilt or new transmission and only one high mileage used one. Are these transmissions for a 2010 Challenger unavailable? Any alternatives or suggestions?
